In order to recover from disease and improve health, patients choose different forms of treatment and care. A delay at any stage could be detrimental, leading to psychological, social or medical complications.
Research form the West has shown that general practitioners (GP) are the gatekeepers to specialised psychiatric services. This is similar to a model constructed by Goldberg and Huxley, proposing that patients have to pass through three filters in order to reach specialised mental health care (community-GP-psychiatric care).
In Pakistan, there are three main mental health service providers: the specialists in private sector, the government and traditional healers. Most of the government run mental health facilities are urban, mismanaged, poorly resourced and understaffed with irregular provision of medications. Generally, the poorest sections of the society visit these hospitals since they have no other options available. The rest prefer treatment from private medical specialists.
But even that has its own problems. It is unregulated while monetary exploitation and abuse of patients is not uncommon. This is particularly so in patients with schizophrenia, which leads to delay, thereby increasing the psychosocial morbidity and burden of illness. This is further compounded by the extreme dearth of psychiatrists and other mental health professionals in the country. For example, it is estimated that there are only 360 psychiatrists for a population of 160 million.
According to the World Health Organization (WHO), mental healthcare services should be integrated with general health services and provided in a decentralised manner. It is also beleived that trained health professionals are scarce in developing countries. If proper health care is to be brought within reach of the masses, primary healthcare physicians must work in collaboration with specialised personnel.
Research from the West and developing countries shows that about a quarter to half of the patients in primary care have mental health needs that have not been addressed. Due to poor awareness and resources, primary care staff has not been trained to treat and manage mental illness, thereby fulfilling the need-supply gap. This model was conceived by psychiatrists in the western countries with administrative convenience and well-established primary healthcare system.
In Pakistan, primary health is poorly developed with weak referral chain from primary to secondary to tertiary care services. Most patients by-pass the primary care services and access services at secondary and tertiary care centres directly. The main reason is the poor quality of services offered. Additionally, in the absence of any kind of health insurance, most patients pay out of their own pockets.
Studies on integration of mental health services in primary care centres in Pakistan are inconclusive. The issues involved are related to the perception of government-run primary health care services as well as the costs involved, knowledge of services, stigma, pathways to care and design issues.
A few years ago WHO and Pakistan medical and research council (PMRC) did a survey in order to study the reasons behind the poor utilisation of available BHU services. Low numbers and attendance rate of doctors (63.8 per cent), non-availability of medicines (22 per cent), geographic inaccessibility and low quality of services were some of the major factors. Public sector tertiary care hospitals (TCH) are a major recipient of government budgetary allocation, leaving little resources for improvement in the available primary health care infrastructure. Employees’ salary comprise 55 to 66 per cent of the budget, leaving little room for technological advancement, equipment and medicines.
Integration of mental healthcare in ailing primary care system is a difficult issue which may seem feasible for countries with well-established primary healthcare system. Nearly half a decade of research on pathways to psychiatric care in Pakistan has shown different, yet interesting trends.
For example, a pathway to psychiatric care study from a tertiary care hospital demonstrates that among 96 patients, only 2.8 pre cent were referred by primary care physician as opposed to 20 per cent referral from specialists in other fields of medicine. In this study 63 per cent cases were self/family referred. Only 17 per cent patients had a primary care physician. Clearly, the expected model of primary to tertiary referral care appears to be lacking at a practical level. In this study the principal referral path in Pakistan appeared to be word-of-mouth rather than primary care.
A substantial time period is lost before initiation of treatment in schizophrenia, which is labelled as duration of untreated psychosis (DUP). In the absence of a well-developed primary healthcare system, a majority of patients visit psychiatrists as their first contact. Time is lost due to non-recognition of prodromal symptoms and subsequently, inadequate treatment. Primary care system, which is competent and motivated, needs to be created while specialists must play their role in training and supervising this mass of generalists.
The prevalent apathy in public and private sector is primarily because of lack of awareness and the stigma related to mental illnesses; a perception which needs to be changed. An active public-private partnership could be a workable solution for mental health service provision. This requires a unified agenda and commitment from both tiers. Any lasting solution must address the deep rooted inequities, ethical misconducts and macroeconomic issues.
