Other hospitals followed, almost entirely supported by private donation, occasional lotteries or the proceeds of public entertainments; for instance, the first performance of Handel's Messiah was given in aid of the Hospital for Incurables, which was sponsored by the Charitable Musical Society. In 1744/5 Ireland had the first maternity hospital in the British Isles, locally known as the Rotunda, taking its name from the Assembly Rooms, whose entertainments supported it.
Where Dublin led, the rest of the country followed. As with the Dublin hospitals, those throughout the country were largely the result of private enterprise and public subscription. Occasionally parliament voted a small grant to a specific hospital.
Then, in an Act of 1765 amended in 1767 (0662), parliament attempted to provide a framework for the development of county infirmaries and, although the facilities and accommodation were totally inadequate to the need, by the end of the century almost every county had its infirmary. Many of the hospitals established under these acts are still extant today. The 1765 legislation acknowledged the inadequacy of the funding for the existing public infirmaries at Dublin, namely the Charitable Infirmary, Mercer's and the Hospital for Incurables, as well as the two public infirmaries at Cork, the North and South Infirmaries, and made provision for £50 p.a. to be paid out of the Treasury to supplement their budgets.
The statutes made the clergy of the Church of Ireland a perpetual corporation for the erection of infirmaries, and qualifications were laid down for additional governors by subscription. Parliament allocated £100 for the surgeon's salary and the Grand Jury was to supplement this with a grant towards the hospital's expenses. It was hoped that private charity would provide the remainder, and in some cases it did. For example, by the end of the century Belfast had in addition to a general infirmary a Fever Hospital, both largely dependent on public support.
Nevertheless, no hospital system was successful before the development of antiseptics and the improvement of medical and nursing training in the nineteenth century. The dispensary system, which offered an outpatient medical service, emerged in the closing decades of the eighteenth–century. It probably gave more effective medical service to greater numbers.
