We aimed to explore participant perspectives on social prescribing (SP) for mental health and well-being and the acceptability of community pharmacists (CP) as members of SP pathways that support people with mild to moderate depression and anxiety.
Background:
SP aims to support people with poor health related to socio-demographic determinants. Positive effects of SP on self-belief, mood, well-being, and health are well documented, including a return to work for long-term unemployed.
Methods:
The study was set in a city in southwest England with diverse cultural and socio-demographics. We recruited SP stakeholders, including CP, to either one of 17 interviews or a focus group with nine members of the public.
Findings:
An inductive iterative approach to thematic analysis produced four superordinate themes: (1) offering choice a non-pharmacological option, (2) supporting pharmacy communities – ‘it is an extension of what we do’, (3) stakeholder perspectives – pharmacists are very busy and their expertise unknown by some, and (4) potential for pharmacy in primary care.
Stakeholders viewed CP as local to and accessible by their community. Pharmacists perceived referral to SP services as part of their current role. General practitioner participants considered pharmacy involvement could reduce their workload and expand the primary healthcare team. Importantly, general practitioners and CP viewed SP as a non-pharmacological alternative to prescribing unnecessary antidepressants and reduce associated adverse effects. All participants voiced concerns about pharmacy dispensing busyness as a potential barrier to involvement and pharmacists requesting mental health training updates.
Key findings suggest CP offer a potential alternative to the general practitioner for people with mild to moderate depression and anxiety seeking access to support and health information. However, CP need appropriately commissioned and funded involvement in SP, including backfill for ongoing dispensing, medicines optimization, and mental health first aid training.
This paper presents the development of the METRIC toolkit, aimed at enhancing primary healthcare interventions in the context of hepatitis C control, thus contributing to the World Health Organization’s global strategy to achieve the elimination of the disease by 2030.
Background:
At the global level, most people living with hepatitis C are unaware of their condition. As such, the eradication of hepatitis C necessitates comprehensive strategies within primary healthcare settings, as it provides an opportunity to reach the general population, facilitates the identification of potential patients who may be unfamiliar with hepatitis C, and guides them toward adequate care. Herein, we propose the METRIC toolkit as a means to optimize the efficiency and efficacy of healthcare services dedicated to hepatitis C control.
Methods:
The development of the METRIC toolkit was guided by a thorough review of pertinent literature, focusing on primary healthcare interventions in hepatitis C control. Key components were identified, encompassing systematic problem identification, solution formulation, outcome evaluation, and feedback integration.
Findings:
The METRIC toolkit represents a valuable resource for strengthening primary healthcare interventions in hepatitis C control. By fostering a culture of continuous improvement and data-driven decision-making, this framework holds promise in advancing the global agenda towards hepatitis C elimination. However, its successful application requires careful consideration of contextual factors and ongoing adaptation to local needs and circumstances.
Clinician acceptance influences technology adoption, but UK health professionals' attitudes towards artificial intelligence (AI) in hearing healthcare are unclear. This study aimed to address this knowledge gap.
Methods
An online survey, based on the Checklist for Reporting Results of Internet E-Surveys, was distributed to audiologists, ENT specialists and general practitioners. The survey collected quantitative and qualitative data on demographics and attitudes to AI in hearing healthcare.
Results
Ninety-three participants (mean age 39 years, 56 per cent female) from three professional groups (21 audiologists, 24 ENT specialists and 48 general practitioners) responded. They acknowledged AI's benefits, emphasised the importance of the clinician–patient relationship, and stressed the need for proper training and ethical considerations to ensure successful AI integration in hearing healthcare.
Conclusion
This study provides valuable insights into UK healthcare professionals' attitudes towards AI in hearing health and highlights the need for further research to address specific concerns and uncertainties surrounding AI integration in hearing healthcare.
This study aims to investigate the knowledge of rural general practitioners (GPs) in esophageal cancer (EC) prevention and treatment in China and analyze relevant influencing factors, so as to improve the ability of rural GPs in EC prevention and treatment.
Methods:
This cross-sectional study was conducted from November 5, 2021, to November 20, 2021. A self-designed questionnaire was used to conduct an online survey. Multivariable logistic regression models were used to identify the influencing factors of knowledge proficiency of GPs in rural China for EC prevention and treatment.
Results:
This study included 348 participants from 12 rural areas in Hebei Province. The mean accuracy rate on all question items was 42.3% ± 10.67%. Sex (OR = 2.870, 95% CI: 1.519–5.423), educational level (OR = 3.256, 95% CI: 1.135–9.339), and comprehension of clinical practice guidelines for EC (OR = 4.305, 95% CI: 2.023–9.161) were significant predictors for GPs’ knowledge proficiency of EC prevention and treatment (P < 0.05).
Conclusions:
The study indicated that knowledge proficiency of rural GPs of EC prevention and control still awaits to be improved. Sex, educational level, and comprehension of clinical practice guidelines for EC were significant predictors for their proficiency.
This study aimed to assess current levels of knowledge, opinions and attitudes regarding mental health among the local cohort of general practitioner trainees (n = 45) working in Malta. A questionnaire adapted from the Mental Health Literacy Scale was used. Data were analysed using one-way analysis of variance and Pearson correlation tests.
Results
All participants had scores equal to or more than the mean score in their knowledge and confidence assessments; 51% of the participants achieved the maximum score for a very positive attitude towards mental health, with such scores found particularly among female trainees. Increased levels of knowledge are associated with a more positive attitude, which can in turn lead to greater acceptance and reduce stigma.
Clinical implications
Knowledge is a powerful tool for reducing stigma and improving the doctor–patient relationship, indicating that regular training initiatives are necessary to equip budding general practitioner specialists with the necessary skills and confidence.
Some symptoms are recognised as red flags for cancer, causing the General Practitioner (GP) to refer the patient for investigation without delay. However, many early symptoms of cancer are vague and unspecific, and in these cases, a delay in referral risks a diagnosis of cancer that is too late. Empowering GPs in their management of patients that may have cancer is likely to lead to more timely cancer diagnoses.
Aim:
To identify the factors that affect European GPs’ empowerment in making an early diagnosis of cancer.
Methods:
This was a Delphi study involving GPs in 20 European countries. We presented GPs with 52 statements representing factors that could empower GPs to increase the number of early cancer diagnoses. Over three Delphi rounds, we asked GPs to indicate the clinical relevance of each statement on a Likert scale.
The final list of statements indicated those that were considered by consensus to be the most relevant.
Results:
In total, 53 GPs from 20 European countries completed the Delphi process, out of the 68 GPs who completed round one. Twelve statements satisfied the pre-defined criteria for relevance. Five of the statements related to screening and four to the primary/secondary care interface. The other selected statements concerned information technology (IT) and GPs’ working conditions. Statements relating to training, skills and working efficiency were not considered priority areas.
Conclusion:
GPs consider that system factors relating to screening, the primary-secondary care interface, IT and their working conditions are key to enhancing their empowerment in patients that could have cancer. These findings provide the basis for seeking actions and policies that will support GPs in their efforts to achieve timely cancer diagnosis.
General Practitioners (GPs) are inevitably involved when disaster strikes their communities. Evidence of health care needs in disasters increasingly suggests benefits from greater involvement of GPs, and recent research has clarified key roles. Despite this, GPs continue to be disconnected from disaster health management (DHM) in most countries.
Study Objective:
The aim of this study was to explore the perspectives of disaster management professionals in two countries, across a range of all-hazard disasters, regarding the roles and contributions of GPs to DHM, and to identify barriers to, and benefits of, more active engagement of GPs in disaster health care systems.
Methods:
A qualitative research methodology using semi-structured interviews was conducted with a purposive sample of Disaster Managers (DMs) to explore their perspectives arising from experiences and observations of GPs during disasters from 2009 through 2016 in Australia or New Zealand. These involved all-hazard disasters including natural, man-made, and pandemic disasters. Responses were analyzed using thematic analysis.
Results:
These findings document support from DM participants for greater integration of GPs into DHM with New Zealand DMs reporting GPs as already a valuable integrated contributor. In contrast, Australian DMs reported barriers to inclusion that needed to be addressed before sustained integration could occur. The two most strongly expressed barriers were universally expressed by Australian DMs: (1) limited understanding of the work GPs undertake, restricting DMs’ ability to facilitate GP integration; and (2) DMs’ difficulty engaging with GPs as a single group. Other considerations included GPs’ limited DHM knowledge, limited preparedness, and their heightened vulnerability.
Strategies identified to facilitate greater integration of GPs into DHM where it is lacking, such as Australia, included enhanced communication, awareness, and understanding between GPs and DMs.
Conclusion:
Experience from New Zealand shows systematic, sustained integration of GPs into DHM systems is achievable and valuable. Findings suggest key factors are collaboration between DMs and GPs at local, state, and national levels of DHM in planning and preparedness for the next disaster. A resilient health care system that maximizes capacity of all available local health resources in disasters and sustains them into the recovery should include General Practice.
The incidence of gout has increased rapidly in recent years, and the suspected lack of awareness of gout among general practitioners may lead to misdiagnosis and inappropriate treatment.
Aim:
To assess general practitioners’ management of gout at community health service clinics in the Tongzhou district of Beijing, as well as the factors that contributed to optimal decision making.
Methods:
A survey based on current guidelines for assessment and management of gout was sent to 245 general practitioners at community health service clinics in the Tongzhou district of Beijing. The questionnaire included personal information of general practitioners and ten items that addressed knowledge of gout. Our questionnaire was self-administered and distributed electronically via WeChat, and data were collected on a platform called ‘Wenjuanwang’. Statistical analysis was performed using SPSS version 19.0 software.
Results:
Totally, 216 general practitioners responded to the survey. About three-quarters (71.8%) reported having received Continuing Medical Education (CME) about gout. More than half (54.6%) reported an awareness of treat to target (T2T) for gout. However, the overall rate of good understanding of gout was only 6.5%, a basic knowledge of gout was 55.6%, and understanding about gout diagnosis and treatment was only 11.1%. The general practitioners’ understanding of basic concepts related to gout indicated that CME could improve their understanding (P < 0.05). An analysis of the general practitioners’ rate of comprehension of gout diagnosis and treatment showed that education level, CME, and familiarity with T2T could improve understandings of gout diagnosis and treatment (P < 0.05).
Conclusion:
There are serious deficits in understandings about gout among general practitioners in the Tongzhou district of Beijing. Quality CME is needed to improve Chinese general practitioners’ management of gout.
Malnutrition is common among older adults and is associated with a progressive decline in overall health and increased mortality. With a rapidly ageing population, the detection, prevention and management of malnutrition require urgent attention within health service planning and delivery. Routine screening for malnutrition among older adults in community settings, which addresses aetiological as well as phenotypic factors, is considered an important step for prevention and early intervention. The aim of this review is to summarise current malnutrition screening literature and highlight research that seeks to understand and address community-based approaches to malnutrition screening and management. Key healthcare professionals (HCPs) that encounter community-dwelling older adults include general practitioners (GPs), community-based nurses, community pharmacists and a range of other health and social care professionals including dietitians, physiotherapists, speech and language therapists, and occupational therapists. The key barriers to implementing screening in primary care include lack of knowledge about malnutrition among non-dietetic HCPs, lack of resources allocated to managing malnutrition, lack of access to dietetic services, and poor GP knowledge about oral nutritional supplement prescribing. In addition, older adults have poor insight into the clinical condition and the associated negative health implications. Investment in education among HCPs and public awareness is required, as well as accompanying resources to successfully implement malnutrition screening programmes for community-dwelling older adults.
This cross-sectional study is the first one to explore the collaboration of the influencing factors thereof amongst general practitioners (GPs) and gynaecologists (Gyns) working in primary care in urban and rural settings in Germany.
Background:
The number of women aged ≥ 50 years is predicted to increase in the next years in Germany. This coincides with the ageing of primary care specialists providing outpatient care. Whereas delegation of tasks to nurses as a form of interprofessional collaboration has been the target of recent studies, there is no data regarding collaboration amongst physicians in different specialisations working in primary care. We explored collaboration amongst GPs and Gyn regarding the healthcare provision to women aged ≥ 50 years.
Methods:
A quantitative postal survey was administered to GPs and Gyns in three federal states in Germany, focusing on care provision to women aged ≥ 50 years. A total of 4545 physicians, comprising 3514 GPs (67% of the total GP population) randomly selected, and all 1031 Gyns practicing in these states received the postal survey in March 2018. A single reminder was sent in April 2018 with data collection ending in June 2018. Multiple logistic regressions were performed for collaboration, adjusted by age and sex, alongside descriptive methods.
Findings:
The overall response rate was 31% (1389 respondents): 861 GPs (25%) and 528 Gyns (51%), with the mean respondent age being 54.4 years. Seventy-two per cent were female. Key competencies of collaboration are associated with working in rural federal states and with network participation. Physicians from rural states [odds ratio (OR) = 1.5, 95% confidence interval (CI) = 1.2, 1.9] and physicians in networks (OR = 3.0, CI = 2.3, 3.9) were more satisfied with collaboration. Collaboration to deliver services for women aged ≥ 50 years is more systematic amongst GPs and Gyns who are members of a network; increased networking could improve collaboration, and ultimately, outcomes too.
In France about 10,000 suicides/year are recorded. General practitioners (GPs) have an important role in prevention, with consultation rates between 20% and 76% the day preceding suicide. StopBlues is an application/website for primary prevention of suicide in the general population. Its promotion was supported by municipalities and involved GPs.
Objectives
To evaluate how the involvement of GPs in the promotion of StopBlues had an impact on its utilization.
Methods
StopBlues was promoted in 25 French municipalities randomly assigned to a ‘basic’ promotion group organized by municipalities only or an ‘intensified’ promotion group that also includes promotion in GPs’ waiting rooms. StopBlues users were asked how they found out about StopBlues. After two years, an ad hoc questionnaire was sent to all GPs (N=2,111).
Results
StopBlues users from those municipalities (N=885) were 16% to learn about StopBlues from GPs, 93% of them living in municipalities with ‘intensified’ promotion. In the ‘basic’ group, where no GPs have heard about StopBlues, 15% would like to know more about it/will have a look at it and 8% will use it and recommend it to colleagues. Half of GPs from the ‘intensified’ group had heard about the program, with 24% who recommended StopBlues to some patients. 21% of GPs agreed that they will use it and recommend it to colleagues.
Conclusions
Involving GPs in the use of e-health tools is of major interest to improve their utilization. Our results show that GPs are in need of those in dealing with patients with psychological pain/distress.
The global COVID-19 pandemic has disrupted healthcare worldwide. In low- and middle-income countries (LMICs), where people may have limited access to affordable quality care, the COVID-19 pandemic has the potential to have a particularly adverse impact on the health and healthcare of individuals with noncommunicable diseases (NCDs). A World Health Organization survey found that disruption of delivery of healthcare for NCDs was more significant in LMICs than in high-income countries. However, the study did not elicit insights into the day-to-day impacts of COVID-19 on healthcare by front-line healthcare workers (FLHCWs).
Aim:
To gain insights directly from FLHCWs working in countries with a high NCD burden, and thereby identify opportunities to improve the provision of healthcare during the current pandemic and in future healthcare emergencies.
Methods:
We recruited selected frontline healthcare workers (general practitioners, pharmacists, and other medical specialists) from nine countries to complete an online survey (n = 1347). Survey questions focused on the impact of COVID-19 pandemic on clinical practice and NCDs; barriers to clinical care during the pandemic; and innovative responses to the many challenges presented by the pandemic.
Findings:
The majority of FLHCWs responding to our survey reported that their care of patients had been impacted both adversely and positively by the public health measures imposed. Most FLHCs (95%) reported a deterioration in the mental health of their patients.
Conclusions:
Continuity of care for NCDs as part of pandemic preparedness is needed so that chronic conditions are not exacerbated by public health measures and the direct impacts of the pandemic.
Rising antimicrobial resistance (AMR) in primary care is a growing concern and a threat to community health. The rise of AMR can be slowed down if general practitioners (GPs) and community pharmacists (CPs) could work as a team to implement antimicrobial stewardship (AMS) programs for optimal use of antimicrobial(s). However, the evidence supporting a GP pharmacist collaborative AMS implementation model (GPPAS) in primary care remains limited.
Aim:
With an aim to design a GPPAS model in Australia, this paper outlines how this model will be developed.
Methods:
This exploratory study undertakes a systematic review, a scoping review, nationwide surveys, and qualitative interviews to design the model. Medical Research Council (MRC) framework and Normalization Process Theory are utilized as guides. Reviews will identify the list of effective GPPAS interventions. Two AMS surveys and paired interviews of GPs and CPs across Australia will explore their convergent and divergent views about the GPPAS interventions, attitudes towards collaboration in AMS and the perceived challenges of implementing GPPAS interventions. Systems Engineering Initiative for Patient Safety (SEIPS 2.0) model and factor analyses will guide the structure of GPPAS model through identifying the determinants of GPPAS uptake. The implementable GPPAS strategies will be selected based on empirical feasibility assessment by AMS stakeholders using the APEASE (Affordability, Practicability, Effectiveness and cost-effectiveness, Acceptability, Side-effects and safety, Equity) criteria.
Discussion:
The GPPAS model might have potential implications to inform how to better involve GPs and CPs in AMS, and, to improve collaborative services to optimize antimicrobial use and reduce AMR in primary care.
Complicated grief is a debilitating condition that individuals may experience after losing a loved one. General practitioners (GPs) are well positioned to provide patients with support for grief-related issues. Traditionally, Irish GPs play an important role in providing patients with emotional support regarding bereavement. However, GPs have commonly reported not being aptly trained to respond to bereavement-related issues. This study explores GPs’ current knowledge of and practice regarding complicated grief.
Methods:
A qualitative study adopting a phenomenological approach to explore the experiences of GPs on this issue. Semi-structured interviews were carried out with a purposive sample of nine GPs (five men and four women) in Ireland. Potential participants were contacted via email and phone. Interviews were audio-recorded, transcribed and analysed using Braun & Clarke’s (2006) model of thematic analysis.
Results:
GPs had limited awareness of the concept of complicated grief and were unfamiliar with relevant research. They also reported that their training was either non-existent or outdated. GPs formed their own knowledge of grief-related issues based on their intuition and experiences. For these reasons, there was not one agreed method of how to respond to grief-related issues reported by patients, though participants recognised the need for intervention, onward referral and review.
Conclusions:
The research highlighted that GPs felt they required training in complicated grief so that they would be better able to identify and respond to complicated grief.
Dementia in the elderly constitutes a growing challenge in healthcare worldwide, including Hungary. There is no previous report on the role of general practitioners in the management of dementia.
Aim:
The purpose of the present study was to investigate the Hungarian general practitioners’ attitude toward their patients living with dementia as well as dementia care. Our goal was also to assess their willingness and habits in assessing dementia. Additionally we wanted to explore the role of education about dementia, and its impact on their attitude in dementia management.
Methods:
As part of a large survey, a self-administered questionnaire was filled out voluntarily by 402 of general practitioners. According to our preset criteria, 277 surveys were selected for evaluation. Descriptive statistical analysis and Likert-scale analysis were performed.
Findings:
Half of the doctors (49.8%) indicated that they conducted a test to assess cognitive functions in case of suspicion. Among the respondents who did not assess, 50.0% of physicians cited lack of time as the main reason for not doing so and 14.4% of them had not proper knowledge of testing methods. The respondents most often mentioned feelings toward their patients with dementia, were regret (Likert-scale mean: 3.33), helplessness (3.28) and sadness (3.07). The majority of physicians thought the treatment of dementia was difficult (4.46). Most of the respondents (81.2%) indicated that in the past 2 years they had not participated in any training about dementia. Those practitioners who had participated in some form of education were less likely to feel helpless facing a patient with dementia, and education also determined their approach to dementia care.
Aim of the present study was to assess the knowledge of the potential role of nurses in the primary care setting and to analyse the attitudes towards their utilization by nurses and General Practitioners (GPs) in a region of Italy.
Background
Nowadays, in Italy, the role of the nurse in primary care is still under-recognized and most primary care medical offices are managed individually by a physician.
Methods
The study consists of a questionnaire-based cross-sectional survey carried out in Piedmont, Italy, between February and September 2015.
Findings
We included 105 participants, 57 nurses and 48 physicians. The presence of a nurse working together with the GP was defined as ‘useful’ by 54.4% of nurses (versus 60.4% of physicians), as ‘essential’ by 45.6% of nurses (versus 25.0% of physicians), as ‘marginal’ by no nurses (versus 14.6% of physicians) and as ‘unimportant’ by none (P=0.002). Thus, physicians seemed to be less favorable towards a full collaboration and power-sharing with nurses. Furthermore, GPs and nurses showed a different attitude towards the role of nurses in primary care: while nurses highlighted their clinical value, physicians tended rather to recognize them a ‘supportive’ role. Moreover, only 20.8% of the physicians interviewed stated that they worked with a nurse. At the multivariate analysis, the age class resulted to be a significant predictor of the perception that the presence of a nurse working with the GP is essential: participants >50 years had an OR of 0.03 (P=0.028). Although the primary care organization appears still largely based on a traditional physician-centric care model, the positive attitude of nurses and young GPs towards a more collaborative model of primary care might represent a promising starting point.
The general practitioner is an important figure in the provision of medical care during radiation incidents and cases of radiological terrorism. Knowing the nature of the radiation injury is essential for correct diagnosis and treatment. Insufficient knowledge of most physicians, and of general practitioners in particular, on the clinical manifestation of radiation injuries is the reason such conditions remain unrecognized and improperly treated. We suggest some simple diagnostic criteria for assessment of the injured by general practitioners, based on the results of our own studies and on the recommendations of prominent international organizations. (Disaster Med Public Health Preparedness. 2018;12:507–512)
This study aims to assess the knowledge, attitude and practice of primary care physicians (PCPs) in Lebanon regarding nutrition counseling and to investigate possible related barriers.
Background
Nutrition counseling is an important aspect of patient care, especially with the increase in nutrition-related disorders.
Methods
This is a descriptive study among a convenience sample of PCPs in Lebanon at two annual conferences in 2014 using an anonymous questionnaire.
Findings
Response rate was 54.6%. Overall, physicians considered that they have good to very good nutritional knowledge. Although they rated their formal nutritional education poorly, they had a positive attitude towards nutritional counseling and reported practicing general nutritional counseling with their patients. Barriers to nutritional counseling were: time, perceived poor patient adherence to diet, gap in physician’s nutritional knowledge and lack of insurance coverage for dietitian fees. Changes should be made to medical education curricula to include nutrition courses related to prevalent health problems.
To determine the proportion of UK surfers aware of external auditory canal exostosis, to identify surfer characteristics associated with knowledge of the condition and to explore attitudes to earplug use.
Method:
An online, cross-sectional survey of UK-based surfers.
Results:
Of 375 surfers, 86.1 per cent (n = 323; 95 per cent confidence interval = 82.3–89.3) reported awareness of external auditory canal exostosis. Further investigation revealed that, despite their awareness of the condition, 23.4 per cent of these surfers (88 out of 323; 95 per cent confidence interval = 19.5–28.0) had little or no knowledge about external auditory canal exostosis. Predictors of knowledge included: distance from nearest surfing beach (p = 0.001), surfing standard (ability) (p = 0.008), earplug use (p = 0.024) and positive external auditory canal exostosis diagnosis (p = 0.009).
Conclusion:
The findings suggest that a significant minority of UK surfers have no knowledge about this condition. Knowledge of external auditory canal exostosis was significantly associated with earplug use when surfing. Efforts to improve surfers’ knowledge are required to enable surfers to better protect themselves, which could reduce the incidence of external auditory canal exostosis.
Clinical deficiency of the B-vitamin riboflavin (vitamin B2) is largely confined to developing countries; however accumulating evidence indicates that suboptimal riboflavin status is a widespread problem across the developed world. Few international data are available on riboflavin status as measured by the functional biomarker, erythrocyte glutathione reductase activation coefficient, considered to be the gold standard index. One important role of riboflavin in the form of flavin dinucleotide is as a co-factor for the folate-metabolising enzyme methylenetetrahydrofolate reductase (MTHFR). Homozygosity for the common C677T polymorphism in MTHFR, affecting over 10 % of the UK and Irish populations and up to 32 % of other populations worldwide, has been associated with an increased risk of CVD, and more recently with hypertension. This review will explore available studies reporting riboflavin status worldwide, the interaction of riboflavin with the MTHFR C677T polymorphism and the potential role of riboflavin in personalised nutrition. Evidence is accumulating for a novel role of riboflavin as an important modulator of blood pressure (BP) specifically in individuals with the MTHFR 677TT genotype, with results from a number of recent randomised controlled trials demonstrating that riboflavin supplementation can significantly reduce systolic BP by 5–13 mmHg in these genetically at risk adults. Studies are however required to investigate the BP-lowering effect of riboflavin in different populations and in response to doses higher than 1·6 mg/d. Furthermore, work focusing on the translation of this research to health professionals and patients is also required.
